An example calibration system includes a speed sensor, a steering angle sensor, a calibration unit, and a controller. In some implementations, the calibration unit generates a first plot of a first series of first yaw rate estimates over time based upon signals from the speed sensor and the steering angle sensor, generates a second plot of a second series of second yaw rate estimates over the time based upon signals from at least one inertial measurement unit and compares the first plot and the second plot to determine a steering offset bias that minimizes differences between the first plot and the second plot. The controller outputs control signals to adjust at least one of a steering and propulsion of the tractor based on the steering offset bias. In some implementations, the controller determines an updated tire radius for a tractor tire based upon different estimated tractor speeds.
